Dual-functional reduced graphene oxide decorated nanoporous polytetrafluoroethylene metafabrics for radiative cooling and solar-heating

Abstract

Although passive radiative cooling and active heating are becoming two essential functions for next-generation smart personal thermal management textiles, the integration of opposite cooling and heating into one metafabric with...

Superhydrophobic and mechanical properties enhanced the electrospinning film with a multiscale micro-nano structure for high-efficiency radiation cooling

“…21 Another strategy is to construct micro- and nano-structures in substrates with high emissivity comprised of pore structures, 22–26 core–shell structures, 27–29 and micro-nano fibrous structures. 30–33 It has been demonstrated that nanofibers with a diameter comparable to the wavelength of the solar spectrum can serve as effective scatters to enable strong solar reflection. 34–37 Thus, fibrous films obtained by the electrospinning process have attracted significant attention in the field of radiation refrigeration due to their advantages of easy regulation of the fiber structure, high air permeability and elevated flexibility.…”

Recent advances in dynamic dual mode systems for daytime radiative cooling and solar heating

“…Nevertheless, due to the high solar thermal conversion efficiency of such materials, the heating side in the dual mode system still maintains a temperature above ambient. 86 Examples of such materials include graphene, 87 carbon nanotubes, and carbon black. According to eqn (4), to achieve the temperature increase, the value of P net needs to be less than 0.…”

Dual-functional thermal management textiles for dynamic temperature regulation based on ultra-stretchable spiral conductive composite yarn with 500%-strain thermal stability and durability

“…Liu et al 19 endowed a smart textile with the function of heat storage and temperature regulation by combining phase-change materials with a 3D conductive network in nonwoven PP. Luo et al 20 integrated opposite cooling and heating functions into metafabric by assembling a nanoporous PTFE radiative cooling substrate with a solar-thermal RGO layer and a PDMS supporting coating. However, the use of optical radiation and photothermal effect might create a serious disadvantage since it can cause skin to burn.…”
